The human body magnetic field database, and use the constructed human body magnetic field database as the identification information of its legal owner; wherein, the preset time period includes the first preset time period and the second preset time period, and the first preset time period from 06:00 to 18:00; the second preset time period is from 18:00 to 06:00 the next day; since each person’s body has a different magnetic field, the human body’s magnetic field is a unique biological characteristic of each person, and its Like fingerprints, it can be used as human biometric information for identification. The strength of the magnetic field data of the human body is not constant in each time period. Therefore, in this embodiment, two time periods are preset for the data of the human body magnetic field, that is, the preset time period includes the first preset time period and the first preset time period. The second preset time period, the first preset time period is from 06:00 to 18:00; the second preset time period is from 18:00 to 06:00 the next day;

Step 2: The mobile smart terminal collects the body odor data of its legal owner, receives the fingerprint information and vein information corresponding to each finger of the legal owner, and constructs the body odor database of the legal owner of the mobile smart terminal and the fingerprint information database corresponding to each finger and vein information database; the mobile intelligent terminal gives its legal owner the human body magnetic field with the first priority for identification, and the body odor data with the second priority for identification; in the process of identifying whether the operator has a legal identity, the first Priority has a higher recognition reliability than the second priority; among them, because each person's body odor is different, human body odor data, like biological characteristics such as human magnetic field, fingerprint, face and iris, also have unique and indistinguishable characteristics. Reproducibility, so the body odor data of the human body can also be used as characteristic information for identification; Regarding the priority of human body magnetic field and body odor data in identification, for example, when the mobile smart terminal judges that the obtained operator's human body magnetic field belongs to its legal The magnetic field data of the owner, and when it is judged that the acquired body odor data does not belong to the legal owner's body odor data, the mobile smart terminal will finally determine that the operator is the legal owner;

Step 3, the mobile smart terminal displays a preset number of payment password input boxes on its touch screen to its legal owner, and each payment password input box corresponds to a list of seven basic colors for optional selection; among them, the basic color The seven basic colors in the color list are red, orange, yellow, green, cyan, blue and purple, and each payment password input box corresponds to a group of payment allowable colors; each group of payment allowable colors is the combination of the seven basic colors. Any combination; for example, the mobile smart terminal displays 3 payment password input boxes on its touch screen, and the 3 payment password input boxes are respectively numbered 01 input box, 02 input box and 03 input box; where:

The 01 input box corresponds to the seven basic colors of red, orange, yellow, green, cyan, blue and purple,

The 02 input box corresponds to the seven basic colors of red, orange, yellow, green, cyan, blue and purple,

The 03 input box corresponds to the seven basic colors of red, orange, yellow, green, cyan, blue and purple;

The basic colors provided in the above three payment password input boxes are the same, and the legal owner of the mobile smart terminal can select at least one basic color in the 01 input box as a group of payment permission colors corresponding to the 01 input box, For example, if you choose red alone as a group of payment permission colors, you can also choose a combination of the three basic colors of red, orange and yellow as a group of payment permission colors corresponding to the 01 input box; similarly, the 02 input box and 03 input box You can also select settings in the box according to your needs to form the corresponding payment allowable colors; for example, a group of payment allowable colors corresponding to the 01 input box is red, red and yellow, and a group of payment allowable colors corresponding to the 02 input box are orange and Yellow, a group of payment permission colors corresponding to the 03 input box are blue and purple.

Step 4, according to the basic color list corresponding to each payment password input box on the touch screen, the legal owner of the mobile smart terminal sequentially selects the basic color combination of the number of self-defined types as the payment permission color of each payment password input box, and The mobile smart terminal correspondingly stores the payment permission colors corresponding to each payment password input box; the overall combination of each group of payment permission colors input by the legal owner of the mobile smart terminal in each payment password input box forms the mobile payment password input box. The payment password for the second payment confirmation of the smart terminal; for example, in the three payment password input boxes illustrated in step 3, the second confirmation payment password of the mobile smart terminal is the payment permission color of each group corresponding to the three input boxes. The overall combination, that is, the second confirmation payment password of the mobile smart terminal is "red, red, yellow; orange, yellow; blue, purple".

In addition, as a more secure payment protection method, the secondary confirmation payment password of the mobile smart terminal is the overall combination of each group of payment permission colors entered by the legal owner in sequence in each payment password input box; That is to say, the order of various basic colors also has a limiting effect on the setting of the secondary confirmation payment password.
